2 Power Management Solutions Conductive Particle Foil Adhesive Foil Substrate 3M Charge-Collection Tapes 3M Charge-Collection Solar Tapes consist of tin-plated copper foil with acrylic-based, pressure sensitive adhesives used in thin film solar applications requiring z-axis conductivity. These tapes can be applied at high speeds using automation equipment. Since there is no curing required (as with liquid conductive adhesives) they allow for high productivity during panel manufacturing. Suitable for standard laminating temperatures, these tapes are available in a wide range of configurations for applications as charge collectors of buses within solar panels. Stable electrical performance Compatible with typical lamination processes Tin-plated foil allows for solderability Available in many formats to suit different manufacturing processes Adhesive Substrate PET Dielectric Metal Bus Foil Pressure Sensitive Adhesive 3M Dielectric Tapes 3M Dielectric Tapes perform as reliable insulators when used in conjunction with buses/foils in thin film solar panels. They consist of a polymeric film with acrylic adhesive on one or both sides. These tapes can be applied at high speeds using automation equipment, resulting in high productivity during panel manufacturing. Pressure Sensitive Adhesive Substrate Compatible with typical lamination processes Available in one- and two-sided adhesive versions Available in many formats to suit different manufacturing processes 2

3 Light Management Solutions 3M Solar Light Redirecting Film 3M Solar Light Redirecting Film (LRF) is a microstructured reflective mirror film that is applied over cell tabbing ribbons to recapture light that would otherwise be reflected out of the module. Use of LRF over tabbing ribbons results in % increased module power by increasing the amount of light on the cells, and enabling the use of wider tabbing ribbons, which reduces electrical resistive losses. The product is designed to be easily integrated into automated module assembly processes. Photo courtesy of 3M Cool Mirror Film 3M Cool Mirror Film is an all-polymeric wavelength-selective mirror film designed to reflect wavelengths of high conversion efficiency in PV modules, transmit longer infrared wavelengths, and absorb ultraviolet wavelengths. The film can be used in low-concentration PV (LCPV) configurations to increase the amount of light on PV modules, thus significantly increasing energy production while limiting module heating and UV exposure. Increases in annual energy production of up to 19 46% have been demonstrated versus non-concentrated configurations when using Cool Mirror panels in LCPV configurations*. * Energy production improvement varies depending on latitude of installation, time of year, PV module tilt, and mirror panel tilt. Uncoated Greater amount of light reflected 3M Anti-Reflection Coatings Coated The 3M Anti-Reflection (AR) Coating portfolio includes water-based and solvent-based Less light reflected products that increase front glass transmission, thereby raising solar module efficiency. The products provide a hydrophilic surface, which has been demonstrated to provide a AR Coating degree of anti-soiling performance in the field. Designed specifically for OEM use, the products are applied to glass prior to tempering, which increases the coating s durability and resistance to UV, humidity, and abrasion. The products are formulated to apply uniformly, thus reducing the rate of coating defects. ter amount ht reflected Coated Less light reflected s AR Coating 3
